Typhoon Nangka has weakened this evening as it moves closer towards Japan. The eye of Nangka was last located approximately south of Osaka. Maximum sustained winds are down to 150kph with gusts of up to 185kph. Typhoon Nangka is currently moving north northwestward at 20kph.

Latest satellite image shows the rugged eye of Typhoon Nangka moving closer to the Japanese Mainland. Convective activity has weakened and the overall structure has degraded this evening as Nangka continues to battle dry air and decreasing sea surface temperatures. This is being offset by good radial outflow, slowing down the intensification. The image above also shows the outer rain bands starting to affect parts of Shikoku and Kyushu.
Rainbands will continue to spread across the regions of Japan tonight and into tomorrow. Typhoon Nangka is forecast to make landfall in the island of Shikoku by late Thursday evening or early Friday morning. It will then cross into the Chugoku Region in Kyushu before exiting into the Sea of Japan by Friday evening as a weakening Tropical Storm.
Dangerous conditions will dominate the weather across much of Shikoku and Western Honshu beginning tomorrow and will last through Friday and Saturday. Winds of up to 160kph are possible in Shikoku and high waves are likely along the coast. Rainfall amounts of up to 400mm are also possible in many areas in the region.
We'll have another update tomorrow morning.
